I was thinking about grtting the Neptune RTP. Will It work with the LM-1? When I had the car tuned Jeff had A PLX wide band, I was not sure If I would have to get one to use the logger?
Thanks for you time to help out.

If you're talking about the direct serial logging, simply choose the port for it in preferences in the direct serial logging section of the Ports tab. Then Start Direct Logging in the Datalogging menu. If you want it to be your main wideband input make sure to choose that as your wideband in preferences as well.
